As of October 2023, there is no widely recognized artist by the name of Valentin Ruiz Azner in the music industry. It is possible that this individual may be an emerging artist or a local musician not yet documented in major music histories or databases. If you have specific details or context about the artist, I can help provide information based on that. Otherwise, it might be useful to check more localized resources or recent platforms for updates on new or lesser-known artists.
